Method Detail

read

public DoubleMatrix<String,String> read(InputStream stream)
                                 throws IOException

Specified by:

read in class AbstractMatrixReader<DoubleMatrix<String,String>,Double>

Parameters:

stream - InputStream stream to read from

Returns:

NamedMatrix object constructed from the data file

Throws:

IOException

read

public DoubleMatrix<String,String> read(InputStream stream,
                                        Collection<String> wantedRowNames)
                                 throws IOException

Parameters:

stream - InputStream

wantedRowNames - Set

Returns:

read( stream, wantedRowNames, createEmptyRows ) with createEmptyRows set to true.

Throws:

IOException

read

public DoubleMatrix<String,String> read(InputStream stream,
                                        Collection<String> wantedRowNames,
                                        boolean createEmptyRows,

Parameters:

stream - InputStream

wantedRowNames - Set

createEmptyRows - if a row contained in wantedRowNames is not found in the file, create an empty row filled with Double.NaN iff this param is true.

maxRows -

Returns:

matrix

Throws:

IOException

read

public DoubleMatrix<String,String> read(InputStream stream,
                                        Collection<String> wantedRowNames,
                                        int numberOfColumnsToSkip)

read

public DoubleMatrix<String,String> read(String filename)
                                 throws IOException

Specified by:

read in class AbstractMatrixReader<DoubleMatrix<String,String>,Double>

Parameters:

filename - data file to read from (can be compressed)

Returns:

NamedMatrix object constructed from the data file

Throws:

IOException

read

public DoubleMatrix<String,String> read(String filename,
                                        Collection<String> wantedRowNames)
                                 throws IOException

Read a matrix from a file, subject to filtering criteria.

Parameters:

filename - data file to read from (can be compressed)

wantedRowNames - contains names of rows we want to get

Returns:

NamedMatrix object constructed from the data file

Throws:

IOException

read

public DoubleMatrix<String,String> read(String fileName,
                                        Collection<String> wantedRowNames,
                                        int numberOfColumnsToSkip)
                                 throws IOException

Parameters:

fileName -

wantedRowNames - if null, takes all rows

numberOfColumnsToSkip - how many columns to skip -- not counting the first column. So if you set this to 4, the first four data columns will be skipped. If you set it to zero, only the first column will be skipped.

Returns:

Throws:

IOException
